You can only sensibly do that using a live-CD on the 2nd server.
Because, last time I looked, if you overwrote "important" libraries that 
were in use at the time of overwriting, the server would just crash.
At least, that's what happened with my backup-software back then.

With a live-CD, you could also just pipe "dd" through netcat....
